Radiation from oscillating dipoles immersed in a solid, and radiation-induced luminescence

We have solved Maxwell’s equations for a source, consisting of an oscillating dipole, located in a plane-bounded dielectric half space. Formulas are given for the radiation yield from this source in the region outside the dielectric. The medium is characterized by a local, complex dielectric function ε(ω)=${\epsilon }_1$(ω)+i${\epsilon }_2$(ω). The application of these formulas to the analysis of experimental data on luminescence from solids is discussed, and calculations are presented for aluminum, carbon, silver, copper, and gold.
